ABSTRACT:
Well completion methods using an aqueous polymer composition such as rubber latex in a subterranean formation containing a salt zone. The composition is used to form a protective layer on the salt zone. The layer is substantially impermeable to fluids and prevents them from contacting the salt zone and creating a washed-out area therein. Further, the layer enables a freshwater cement slurry to be used in the well completion operations through the salt zone.
